 Instructions

-These instructions are similar to the quick installation in ``README.rst``.
-This is meant as a supplement, so that the HTML5 frontend is installed
-correctly.
-
-.. code-block:: console
-
-   $ git clone --recursive https://github.com/malept/gmusicprocurator.git
-   $ cd gmusicprocurator
-   $ bower install -p  # Added for frontend installation
-   $ virtualenv venv  # Added for creating a separate virtualenv
-   $ source venv/bin/activate
-   (venv) $ pip install -r requirements.txt
-   (venv) $ python -m gmusicprocurator list_devices --no-desktop
-   # See quick install in README.rst
-   (venv) $ python -m gmusicprocurator runserver
+Create a config file. The location depends on the OS where you're installing
+this app:
+
+OS X:
+    ``~/Library/Application Support/gmusicapi/gmusicprocurator.cfg``
+Linux:
+    ``~/.config/gmusicapi/gmusicprocurator.cfg``
+Windows:
+    *If you want to use this on Windows, let me know. I have no idea whether it
+    will work correctly.*
+
+The contents of the file will look like this:
+
+.. code-block:: python
+
+   GACCOUNT_EMAIL = '[email protected]'
+   GACCOUNT_PASSWORD = 'my-password'
+
+Then run the following (lines that start with ``#`` are comments, not commands):
+
+.. code-block:: shell-session
+
+   # Get the code
+   user@host:Code$ git clone --recursive https://github.com/malept/gmusicprocurator.git
+   user@host:Code$ cd gmusicprocurator
+   # Create a new virtual
+   user@host:gmusicprocurator$ virtualenv venv
+   user@host:gmusicprocurator$ source venv/bin/activate
+   (venv)user@host:gmusicprocurator$ pip install -r requirements.txt
+   (venv)user@host:gmusicprocurator$ python -m gmusicprocurator list_devices --no-desktop
+
+The last command will print out a list of mobile devices that are registered
+with Google Music. Select one of them and add the following to the config file
+from above (substituting ``REPLACE_ME`` with the ID, which is after the colon
+in the device ID printout):
+
+.. code-block:: python
+
+   GACCOUNT_DEVICE_ID = 'REPLACE_ME'
+
+Once the config file is saved, the server can be started.
+
+.. code-block:: shell-session
+
+   (venv)user@host:gmusicprocurator$ python -m gmusicprocurator runserver
+
+By default, it runs at ``localhost:5000``. For assistance on how to change
+these settings, run ``python -m gmusicprocurator runserver --help``.
+
+Currently, the proxy assumes that you know the playlist ID. You can access the
+(XSPF) playlist in the media player of your choice via the URL
+``http://localhost:5000/playlists/$PLAYLIST_ID``, replacing ``$PLAYLIST_ID``
+with the proper playlist ID.
+
+Frontend-specific
+~~~~~~~~~~~~~~~~~
+
+If you want to run the frontend as well, run the following before you start the
+server:
+
+.. code-block:: shell-session
+
+   (venv)user@host:gmusicprocurator$ bower install -p
